DDJ-200 not detected by Mac Book AIR

Hi! 

I just bought the controller DDJ-200. When opening rekordbox (freshly downloaded) and connecting the controller (with usb cable, tried both usb ports), it is not detected by the app. Even though the controller has the light on.

In MIDI Audio, the DDJ-200 is not visible neither.

When checking in the midi audio setting on the MAC, nothing is shown.

Mac version: MAC OS Mojave 10.14.6

Could you help ?
